David Bohm's life involved a series of contradictions. Refused security clearance for work on the atom bomb during World War II, he made critical contributions to the development of the bomb. (Unit: 8)

Rainbow images showing individual neurons fluorescing in different colors. By tracking the neurons through stacks of slices, we can follow each neuron's complex branching structure to create the treelike structures. (Unit: 9)

This recent image from the Chandra x-ray telescope shows the Crab Nebula, the remnant of a supernova explosion seen on earth in 1054 AD that accompanied the formation of a rapidly rotating neutron star at its center. (Unit: 8)

Fritz London was a seminal figure in the early days of quantum mechanics through his pioneering work on the chemical bond, the measurement problem, and to our understanding of superfluidity and superconductivity. (Unit: 8)

The first director of the Los Alamos National Laboratory, Robert Oppenheimer (ca. 1944) was a brilliant theoretical physicist and inspired teacher who became famous for his remarkably effective leadership of the Manhattan Project. (Unit: 8)

Like the condensate, these coupled dancers came together when the music started and continued in a fluid motion next to each other without bumping into each other or stepping on each other's toes. (Unit: 8)

Chandra X-ray telescope image of the Vela supernova remnant shows dramatic bow-like structures produced by the interaction of radiation and electron beams coming from the rapidly rotating neutron star in its center. (Unit: 8)
